Abstract

L'invention concerne un procédé qui, dans un mode de réalisation, consiste à: introduire des particules de polymères de polyester contenant un acétaldéhyde résiduel dans une cuve, à une température comprise entre 130 et 195 °C, pour former un lit de particules à l'intérieur de la cuve; circuler un gaz à travers au moins une partie du lit de particules; et retirer de la cuve les particules épuisées présentant une quantité réduite d'acétaldéhyde résiduel. Dans ce procédé, il n'est pas nécessaire d'introduire un flux chaud de gaz à des débit élevés autres que ceux requis pour chauffer des particules froides à une température suffisante pour désorber l'acétaldéhyde. Le procédé offre plutôt un avantage en ce que, si besoin est, le gaz introduit dans la cuve à de faibles débits et à basses températures peut néanmoins désorber effectivement l'acétaldéhyde dans un laps de temps raisonnable, parce que les particules chaudes chauffent rapidement le gaz à la température des particules.
